Courses and course formats

Hello Moodlers,

I have released 2.7.1.4 of the Grid format.  You can get it from: https://moodle.org/plugins/pluginversion.php?id=7154

Changes:

1.  Fixed CONTRIB-5256.  Thanks to Marius Jugariu for reporting the problem.
2.  Made the arrows easier to find by placing them always 75px from the top.
3.  Added German 'New activity' image.  Thanks to Guido Hornig.
4.  Fixed section 0 editing drop down in Bootstrap v3 themes: https://github.com/gjb2048/moodle-format_grid/issues/9.

Cheers,

Gareth
